Islamabad: Terming the detention of ex-army chief Pervez Musharraf as a ‘humiliating treatment’, a group of Pakistani military officers on Friday staged protest against the government by raising their objections. They also expressed their anger for disqualifying Musharraf from contesting the upcoming general elections.

The former military dictator has been under house arrest at his residence in Islamabad after court’s order in connection with the two cases- declaration of the state of emergency in 2007 and assassination of former prime minister Benazir Bhutto.

A delegation of 75 officers from the Command and Staff College in Quetta expressed their concerns over the treatment being meted out to Musharraf. They expressed their protest during their meeting with members of a committee of the Senate or Upper House of Parliament. The delegation led by Col Saqib Ali Cheema met Mushahid Hussain Sayed, chairman of the Senate Standing Committee on Defence, at Parliament House on Friday.

"The military officers were of the opinion that under the Constitution, the armed forces could not be criticized," a source was quoted as saying by the Dawn newspaper.

The military officers expressed concern at what they described as the "ridiculing of the army as an institution", The News daily reported.

Musharraf, 69, was arrested last week after the Islamabad High Court revoked his bail over the detention of more than 60 judges during the 2007 emergency. He was subsequently arrested by the Federal Investigation Agency over the assassination of Bhutto.

Musharraf is currently being held at his farmhouse, which has been declared a "sub-jail". The former military ruler's legal woes have multiplied since he returned to Pakistan last month after nearly four years in self-exile.

He is also facing charges over the killing of Baloch leader Akbar Bugti in a 2006 military operation and several lawyers have petitioned the Supreme Court to put him on trial for treason for imposing emergency rule.

Over the past few days, several retired generals, including former army chief Mirza Aslam Beg, have expressed concern at the treatment being meted out to Musharraf, who was also barred from contesting for next month's general election.
